Queen Elizabeth II has broken one of the key traditions she has followed since taking the throne in 1952 – wearing the Imperial State Crown for her 2019 Queen's Speech. Instead, she placed it on a table next to her. /VCG Photo

The Imperial State Crown, which is usually worn by the queen for almost every official ceremony, weighs more than one kilogram and is adorned with 2,901 precious stones, so it weighs heavy. /VCG Photo

Given that weight, the 93-year-old monarch chose to wear a George IV State Diadem throughout the ceremony, which is a smaller diamond crown. /VCG Photo

The Queen delivered her annual speech at the 65th State Opening of Parliament in the House of Lords at the Palace of Westminster on Monday, outlining the body's plans for the year. /VCG Photo
